  Abstract

Recently, studies on techniques for increasing spectral efficiency have been actively carried out in recent years when spectrum resources have reached saturation. Single sideband (SSB) modulation method and windowing technique are one of technologies that can increase spectral efficiency. Recently, an SSB-WR-OFDM system combining SSB and WR technologies for multi-carrier had been proposed as a technique for improving spectral efficiency. In a multi-carrier system, the performance and spectral characteristics of the system may deteriorate due to the nonlinearity of high power amplifier (HPA). Therefore, evaluation of the system"s peak-to-average power ratio (PAPR) and spectrum is very important. However, there is no research related to this. Therefore, in this paper, we design SSB-WR-OFDM system combining SSB modulation and WR technology and evaluate its performance and characteristics. Furthermore, performance and characteristics of the SSB-WR-OFDM system were evaluated by applying the DFT-spreading method, well known for PAPR reduction techniques. In this paper, the simulation results are presented quantitatively.
